Ash waste (thousand tons) from Illinois Power coal facilities. Figure 25. CILCO coal usage and S02 emissions (both in tons). Fossil fuel emissions. CILCO's SO2 emissions declined from 87,000 tons in 1970 to 33,000 tons in 1990, primarily because the company installed emission controls at its new facility and switched to lower sulfur coal at all other facilities. The ratio of SO2 emissions to total coal usage dropped signifi- cantly, from in 1970 to a mere in 1990. Data on the other air pollutants were not available for this analysis. SUMMARY Nuclear Power. When the Clinton nuclear plant came on-line in 1987, IP became the second utility in Illinois with nuclear generating capacity. Because the facility is relatively new, sufficient data was not available to develop trends in low-level radioactive waste. In 1960, Illinois utiUties produced more than 42 billion kWh of electricity, 90% of which were generated using coal, using natural gas, and using petroleum. By 1970, coal provided 77% of the statewide fuel mix, natural gas provided 16%, petroleum and nuclear By 1990, total utility generation was billion kWh. Of the total, was generated from coal, from fuel 38.
